Crate numext_fixed_uint

A series of fixed non-negative integer types.

Constructors

This crate provides a series of macros that used to construct fixed uints in compile time.

The input is a string literal, and the macros support several formats of the input:

• A decimal string.
• A binary string with 0b prefix.
• A octal string with 0o prefix.
• A hexadecimal string with 0x prefix.

And you can use any number of _ in the string literal to separate it for more readable.

Examples

use numext_fixed_uint::{u128, U128};

const U128_100: U128 = u128!("100");

fn main () -> ::std::io::Result<()> {
    let x1 = u128!("0b110_0100");
    let x2 = u128!("0o144");
    let x3 = u128!("0x64");
    let y = U128::from(100u8);
    assert_eq!(x1, y);
    assert_eq!(x2, y);
    assert_eq!(x3, y);
    assert_eq!(U128_100, y);
    Ok(())
}
